Terra / EOS AM-1 Solar Array Deployment Sequence
These drawings show the deployment sequence for the Terra solar array (SAA).
The array was deployed immediately after launch, and was critical because without power from the array,
the power from the batteries would rapidly be exhausted.
The solar array generates approximately 7500 watts of power.
The blanket is roughly 16 feet wide by 27 feet long. The SAA rotates once per orbit to continuously face the sun.
This drawing shows the deployment sequence in an isometric view.
The array assembly is shown in red, and the array blanket, which includes the solar cells, is shown in blue.
This drawing shows the deployment sequence looking forward from the aft end of the spacecraft (into the velocity vector).
The array assembly is shown in red, and the array blanket, which includes the solar cells, is shown in blue.
